Hi, it's been about 15 years since I worked with PLC's so I am sure many advances have been made.
Just getting back into it as I have been doing calibrations by hand and a sight glass and want to automate and think it should be simple, I hope.
Here is what I am trying to do, I have a tank that I fill with water 100 cm high hold for 2 min. log the level and temp of the water, then drop 3 cm hold for 2 min etc. then when I reach the bottom change I fill the tank with a differnt temp of water and do it all over again. So is there an inexpensive PLC that can control the valves the pump and has both analog and digital inputs and outputs that is easily programmed since I only have a ladder logic background?
